The inventive method is characterised in that, at the end of the hydrogen silylation reaction, the product formed having formula (I) and the platinum group catalytic metal are recovered. According to the invention, the catalytic metal recovery method is performed under the following conditions: a) the catalytic metal is recovered (1) directly from the reaction medium at the end of the reaction or (2) from the liquid distillation residue comprising the by-products and the platinum group metal, residue obtained after distillation of the reaction medium in order to separate the product having formula (I); b) the catalytic metal is recovered by bringing the reaction medium or the distillation residue into contact with an effective amount of a solid substance that absorbs the platinum group metal; and c) the adsorbent and the platinum group metal are separated so that said metal can be recovered. The invention can be used for the synthesis of 3-chloropropyldimethylchlorosilane with the recovery of the iridium-based catalyst.

    摘要： The invention relates to producing an organo alcoxydialkylsilane by a method which consists in introducing by pouring an alcanol in a dialkylhalogenosilane omega-halogenalkyl+an organic solvent (s) phase mixture and in removing a halogen acid formed by entrainment with the aid of said organic solvent(s) phase and is characterised, in particular (i) by selecting a particular phase of solvent(s), for example based on cyclohexane, (2i) by carrying out an alcanol introduction mode which makes it possible to control the drawing off the halogen acid formed during reaction and by (3i) controlling the halogen acid quantity in a reaction medium. The thus obtained dialkylhalogenosilane omega-halogenalkyl is usable, in particular as an initial product for preparing organosilisic sulphur-containing compounds of general formula (IV) by a sulfidising reaction carried out on a alkali metal polysulfur.
